従来、この種のスタッド形トラックローラ軸受としては、実開平２−４７４１ ７号公報に開示されているものが知られている。図３は、従来のスタッド形トラ ックローラ軸受の正面を示す図であり、図４は、図３のスラストワッシャの側面 を示す図である。 Conventionally, this type of stud-type track roller bearing was developed using the Utility Model Application Publication No. 2-4741. The one disclosed in Publication No. 7 is known. Figure 3 shows a conventional stud type truck. 4 is a front view of the track roller bearing, and FIG. 4 is a side view of the thrust washer in FIG. 3. FIG.
【０００３】 図３及び図４において、このスタッド形トラックローラ軸受は、外輪１１と、 軸１３と、多数のころ１２と、保持器１４と、スラストワッシャ１５と、側板１ ６とから構成されている。0003 3 and 4, this stud-type track roller bearing has an outer ring 11, A shaft 13, a large number of rollers 12, a cage 14, a thrust washer 15, and a side plate 1 It consists of 6.
【０００４】 外輪１１は、断面が厚肉で、その内周面に軌道面１１ａが形成され、その軸方 向両端に軌道面１１ａの直径よりも大きな直径を有する段付き部１１ｂが形成さ れている。軸１３は、外輪１１の軌道面１１ａに対応する軸１３の軌道面１３ａ と、軸方向の一端に前記外輪１１の段付き部１１ｂよりも僅かに小さな径を有す るフランジ部１３ｃと、他端に他部材と結合するためのねじ部１３ｂとを有する 。この軸１３が外輪１１に挿入され、軸１３と外輪１１の軌道面１１ａと１３ａ との間に、多数のころ１２が保持器１４によって間隔を保ちながら軌道面を転動 するよう配置されている。また、軸１３の軌道面１３ａの反フランジ側端面には 中空円盤状の側板１６が軸１３に圧入・固着されている。0004 The outer ring 11 has a thick cross section, has a raceway surface 11a formed on its inner peripheral surface, and has a raceway surface 11a formed in its axial direction. A stepped portion 11b having a diameter larger than the diameter of the raceway surface 11a is formed at both ends of the raceway. It is. The shaft 13 has a raceway surface 13a of the shaft 13 corresponding to the raceway surface 11a of the outer ring 11. and has a diameter slightly smaller than the stepped portion 11b of the outer ring 11 at one end in the axial direction. flange portion 13c, and a threaded portion 13b at the other end for connecting to another member. . This shaft 13 is inserted into the outer ring 11, and the raceway surfaces 11a and 13a of the shaft 13 and the outer ring 11 are A large number of rollers 12 roll on the raceway surface while maintaining intervals between It is arranged so that Further, on the end surface of the raceway surface 13a of the shaft 13 on the opposite flange side, A hollow disk-shaped side plate 16 is press-fitted and fixed to the shaft 13.
【０００５】 また、スラストワッシャ１５は、外輪１１の段付き部１１ｂの側壁面と軸１３ のフランジ部１３ｃの側壁面及び反対側の段付き部１１ｂの側壁面と側板１６の 側壁面との間に回転自在に挿入されている。このスラストワッシャ１５は、図４ に示すように等間隔に略球面形状の凹部１５ａが形成され、この凹部１５ａが潤 滑剤の油溜りとなるように構成されている。[0005] Further, the thrust washer 15 is connected to the side wall surface of the stepped portion 11b of the outer ring 11 and the shaft 13. The side wall surface of the flange portion 13c, the side wall surface of the stepped portion 11b on the opposite side, and the side wall surface of the side plate 16. It is rotatably inserted between the side wall surface. This thrust washer 15 is shown in FIG. As shown in FIG. It is designed to act as a lubricant oil reservoir.
【０００６】 上記構成よりなる従来の軸受では、ミスアライメントがある場合などに、ころ １２のスキューなどにより外輪１１にアキシアル荷重が発生し、スラストワッシ ャ１５と外輪１１の側壁面，軸１３のフランジ部１３ｃの側面及び側板１６の側 面とは滑り接触による負荷がなされ、この滑り摩擦部分での軸受の早期焼付きを 防ぐ構成となっている。[0006] In conventional bearings with the above configuration, when there is misalignment, the rollers Axial load is generated on the outer ring 11 due to the skew of the thrust washer. The side wall surfaces of the carrier 15 and the outer ring 11, the side surface of the flange portion 13c of the shaft 13, and the side of the side plate 16. A load is applied due to sliding contact with the surface, which prevents premature seizure of the bearing at this sliding friction area. It is configured to prevent this.
【０００７】[0007]
しかしながら、従来のスタッド形トラックローラ軸受では、第一に、スラスト 負荷はスラストワッシャ１５の側面と外輪１１の側壁面，軸１３のフランジ部１ ３ｃの側面及び側板１６の側面との滑り接触によりなされるが、従来の軸受では 外輪１１の側壁面との接触面積が小さいので単位面積あたりの負荷が大きくなる ので、スラスト負荷が大きい場合や高速回転の場合には滑り接触部分での軸受の 発熱による焼付きが発生する欠点がある。第二に、従来の軸受のスラストワッシ ャ１５は、略球面形状の凹部１５ａを形成することによって潤滑剤の油溜めとし て軸受の焼付きを防止しようとするものであるが、薄肉なスラストワッシャ１５ の側面にこのような略球面形状の凹部１５ａを設けることにより更に接触部分の 面積が減少するという問題があり、また加工コストがかかるという欠点がある。 第三に、外輪１１の段付き部１１ｂの径と、軸１３のフランジ部１３ｃ及び側板 １６の外径とは、防塵のため僅かなすきまとなるように構成されているが、外輪 １１及びフランジ部１３ｃ等の構成が複雑となり加工コストが多く必要とされる などの欠点がある。 However, in conventional stud-type track roller bearings, the thrust The load is applied to the side surface of the thrust washer 15, the side wall surface of the outer ring 11, and the flange portion 1 of the shaft 13. This is done by sliding contact with the side surface of 3c and the side surface of the side plate 16, but in conventional bearings, Since the contact area with the side wall surface of the outer ring 11 is small, the load per unit area becomes large. Therefore, when the thrust load is large or the rotation is at high speed, the bearing at the sliding contact area may be damaged. There is a drawback that seizure occurs due to heat generation. Second, the thrust washer of conventional bearings The carrier 15 functions as a lubricant oil reservoir by forming a substantially spherical recess 15a. This is intended to prevent the bearing from seizing, but the thin thrust washer 15 By providing such a substantially spherical recess 15a on the side surface of the contact area, the contact area is further improved. There is a problem that the area is reduced, and there is also a disadvantage that processing cost is increased. Third, the diameter of the stepped portion 11b of the outer ring 11, the flange portion 13c of the shaft 13, and the side plate. The outer diameter of 16 is configured to leave a small gap for dust prevention, but the outer diameter 11 and the flange portion 13c, etc., are complicated and require a lot of processing cost. There are drawbacks such as.
【０００８】 そこで、本考案は上記従来技術の欠点に鑑みてなされたもので、接触面積を大 きくして単位面積あたりのアキシアル荷重を小さくできる自己潤滑性のあるスラ ストワッシャを用いて滑り摩擦係数が小さく軸受の摩擦を減少させることができ 、高速回転時における耐焼付き性も向上でき、安価で加工も容易なスタッド形ト ラックローラ軸受を提供することを目的とする。[0008] Therefore, the present invention was devised in view of the above-mentioned shortcomings of the conventional technology, and it increases the contact area. A self-lubricating slug that can reduce the axial load per unit area. By using a sto washer, the sliding friction coefficient is small and the friction of the bearing can be reduced. , the stud type tool is inexpensive and easy to process, with improved seizure resistance during high-speed rotation. The purpose is to provide rack roller bearings.

The shaft 2 has a raceway surface 2a corresponding to the raceway surface 1a of the outer ring 1, a flange portion 2b having a diameter D1 slightly smaller than the diameter D of the outer ring 1 at one end in the axial direction, and a shaft end portion at the other end. It has a threaded portion 2c which is threaded on the outer periphery almost to the center and is used for coupling with other members. This shaft 2 is inserted into the outer ring 1, and between the shaft 2 and the raceway surfaces 2a, 1a of the outer ring 1, a large number of rollers 3 as rolling elements are arranged so as to roll on the raceway surface while maintaining the spacing by a cage 4. has been done. Further, on the end surface of the raceway surface 2a of the shaft 2 on the side opposite to the flange, a side plate 6 in the shape of a hollow disk having approximately the same diameter as the flange portion 2b is press-fitted and fixed to the shaft 2. Further, 7 is a supply path for supplying lubricant to the raceway surface 2a of the shaft 2.
【００１３】 一方、スラストワッシャ５は、中空円盤状で、薄くかつ同一厚さの面を有する シート状に形成されており、直径がフランジ部２ｂの直径Ｄ1 と同径若しくは僅 かに小さな径で形成され、厚さは外輪１の幅Ｃとフランジ部２ｂ，側板６とのす きまを考慮して適宜設定される。このスラストワッシャ５は、自己潤滑性のある 耐熱摺動部材が用いられるが、本実施例では結晶性の熱可塑性高性能エンジニア リングプラスチックスの一種であるポリエーテルエーテルケトン（ＰＥＥＫ）で 形成されている。このポリエーテルエーテルケトン（ＰＥＥＫ）は、耐熱性、強 靭性、耐薬品性に優れており、成形加工が容易である。また、このポリエーテル エーテルケトン（ＰＥＥＫ）に代えてポリアセタール（ＰＯＭ）又はポリアミド （ＰＡ）を用いることもできる。このスラストワッシャ５は、外輪１の側面と軸 ２のフランジ部２ｂの側面及び外輪１の反対側の側面と側板６の側面との間に回 転自在に挿入されている。[0013] On the other hand, the thrust washer 5 is formed into a hollow disc-shaped sheet having a thin surface with the same thickness, and has a diameter that is the same as or slightly smaller than the diameter D1 of the flange portion 2b. The thickness is appropriately set in consideration of the width C of the outer ring 1 and the clearance between the flange portion 2b and the side plate 6. This thrust washer 5 is made of a self-lubricating heat-resistant sliding member, and in this embodiment, it is made of polyetheretherketone (PEEK), which is a type of crystalline thermoplastic high-performance engineering plastic. . This polyetheretherketone (PEEK) has excellent heat resistance, toughness, and chemical resistance, and is easily molded. Moreover, polyacetal (POM) or polyamide (PA) can also be used instead of this polyetheretherketone (PEEK). This thrust washer 5 is rotatably inserted between the side surface of the outer ring 1, the side surface of the flange portion 2b of the shaft 2, the opposite side surface of the outer ring 1, and the side surface of the side plate 6.
【００１４】 上記構成よりなるスタッド形トラックローラ軸受では、ミスアライメントがあ る場合に、ころ３のスキューなどにより外輪１にアキシアル荷重が発生するとき でも、スラストワッシャ５の直径をフランジ部２ｂの直径Ｄ1 と同径若しくは僅 かに小さな径で形成して外輪１の側面との接触面積を大きくしているので、単位 面積あたりのスラスト負荷を小さくすることができるので、滑り摩擦係数が小さ くなり軸受の摩擦も減少させることができる。しかも、スラストワッシャ５の材 料として、成形加工が容易で、耐熱性、強靭性、耐薬品性にも優れたポリエーテ ルエーテルケトン（ＰＥＥＫ），ポリアセタール（ＰＯＭ）又はポリアミド（Ｐ Ａ）を用いるようにしたので、耐焼付き性を向上させることができた。In the stud type track roller bearing having the above configuration, even when there is misalignment and an axial load is generated on the outer ring 1 due to the skew of the rollers 3, the diameter of the thrust washer 5 is adjusted to the diameter D of the flange portion 2b. The outer ring 1 is formed with the same diameter or a slightly smaller diameter to increase the contact area with the side surface of the outer ring 1, so the thrust load per unit area can be reduced, so the sliding friction coefficient is reduced and the bearing Friction can also be reduced. Moreover, as the material for the thrust washer 5, polyetheretherketone (PEEK), polyacetal (POM), or polyamide (PA), which is easy to mold and has excellent heat resistance, toughness, and chemical resistance, is used.

This seal 8 connects the outer ring 1 and the flange portion 2b. It is possible to prevent dirt and the like from entering between the outer ring 1 and the side plate 6 and between the outer ring 1 and the side plate 6.
【００１８】[0018]
以上説明したように本考案によれば、接触面積を大きくして単位面積あたりの スラスト負荷を小さくできる自己潤滑性のあるスラストワッシャを用いるように しているので滑り摩擦係数を小さくして軸受の摩擦を減少させることができ、耐 焼付き性が向上するという効果がある。また、本考案によれば、スラストワッシ ャが中空円盤状で、薄くかつ同一厚さの面を有するシート状に形成されているの で、加工が容易であり安価に構成できる効果がある。また、本考案によれば、外 輪も厚肉で同一幅の円筒状に構成されているので、複雑な加工が不要であり、安 価に構成できる効果がある。 As explained above, according to the present invention, the contact area is increased and the Use a self-lubricating thrust washer that can reduce thrust load.
